Im 16 and have been working with fiberglass for a few months now, but i seem to keep runing into the same problems. i always get small pin holes,and waves in the glass. im thinking that im sanding down the bondo to much what makes the wave. Hopefuly someone can direct the right direction.
here are a few picture of FG jobs ive done for friends.

Use a 3M sponge snading block to sand the project instead of an type of air tools. This will give you alot more control of hoe deep your sanding as well as it will not wave your project. If you want to get rid of the pin hoes, you need to apply a high build primer to fill in the holes.

don't use so much filler. only a very thin layer should be applied. Also from time to time, spray the enclosure with a black paint or filler primer to see any waves and sand them doen. Glazng spot putty or resin/filler can fill holes.
How do you calculate port sizes in fiberglass enclosures? I have an F150 and building the enclosure for three w6 woofers. now the problem (if it is a problem) is i have two woofers underneath the back bench seat and one woofer that T's to the center console. So basically the center console runs right into the enclosure underneath the seat, making a T form enclosure. I made it this way so the woofers use this as one big camber of airspace. I would like to make it ported if i could but i don't know where the port would go and how long the port needs to be. any help would be great!

sanding sucks!
How much air space is in the enclosure and what size are the w6s? If your enclosure is big enough you might be able to port it.
As for location, please post a picture up for us to take a look at it. We could probably locate a good spot from there for you.

10 inch woofers , I don't know about the air space. Probably around 3.cuft I'll try to post pics of it.

I would use a 4" diameter circular port with a flares on each end. My calculations suggest using a 10" long port (doesn't have to be straight, it can be bent) This is tuned for about 29Hz and will peak at about 50Hz.
As for location, again pictures would be very helpful, but I would place it as in-between the subs as possible but still keep it fully open. (ie imagine a triangle drawn from the centers of the subs. Then as close to the middle of the triangle that is still fully exposed.
The size of the enclosure is about right to be worked with as a ported enclosure (maybe even a little on the larger side if it is 3cf)... The response curve may be a little funny but without seeing it and testing, I can't be for sure.

eprush7, go check out
www.fiberglassforums.com and spend a few days reading all the info over there. lots of good threads about how to fiberglass and what materials to stay away from. basically anything that has the bondo brand on it is crap.
